I am new to CNC and have recently purchased a Sainsmart laser. The information I have says it is a stb5100 controller. The laser came with software that is difficult for me to use, but the controller connects to my computer. I downloaded Lightburn and am excited by its apparent ease of use. However, it will not connect to my laser. I have tried to automatically connect, and manually connect with a variety of combinations of options of ports and language combinations, with no success.
What should be my next steps.
